We have been drilling wells in the Santa Barbara, Ventura & Los Angeles Counties for nearly 100 years.
We are family-owned, and have 3 generations on staff. We have been in the water well industry since 1926 when my Great Grandfather bought a home built rig and drilled his first well with his two sons (Ralph Sr. and William Hansen).

Hansen Well Service is committed to the customer service and quality only a small family owned company can provide. Along with quality we provide the versatility of a larger corporation. Our expertise lies in groundwater. We have thousands of hours of experience in all types of domestic and environmental water well applications. Our personnel are highly trained in all operations. We have the latest technology in pumping and monitoring systems. If you have a project which requires top quality we are the best in the industry. >>More

Water Well Design

Good well design prioritizes important information

Intended use

Incorporates exploratory borehole data with background information

Economics – construction and pumping costs

The water well design phase is where all the data generated during the preliminary phases of the project are drawn together. There are many projects where key elements are unavailable, it is necessary call on experience gained from completing similar water wells. Accurate records and uniform field procedures can greatly increase a water wells chances of success. >>More

Choosing a location

The well casing should terminate above ground and the ground surface at the well site should be built up when necessary so that surface water will drain away from the well in all directions. A well should be located so it will be accessible for pump repair, cleaning, treatment, testing and inspection. The top of the well should not be within a basement nor under a building with no basement. When adjacent to a building, the well should be at least five feet outside any projection, such as overhanging eaves.
Minimum distances from a well to possible sources of pollution should be great enough to provide reasonable assurance that subsurface flow of contaminated water will not reach the well. Minimum safe distances vary so much with the character of subsurface formations that arbitrarily fixed distances cannot be established. >>More

Well Facts

The earth’s total allotment of water has a volume of about 344 million cubic miles. Of this:
— 315 million cubic miles (93%) is sea water.
— 9 million cubic miles (2.5%) is in aquifers deep below the earth’s surface.
— 7 million cubic miles (2%) is frozen in polar ice caps.
— 53,000 cubic miles of water pass through the planet’s lakes and streams.
— 4,000 cubic miles of water is atmospheric moisture.
— 3,400 cubic miles of water are locked within the bodies of living things. >>More

Well System Annual Inspection

There are a lot of things happening in the background when you open up your faucet: electrical points engage, mechanical springs sense fluctuations in pressure, air bladders push the water towards the opened outlet, check valves open and close. All of these things and more have to work reliably every time you use water.But as long as water keeps coming out of the faucet, we don’t even think about it until we turn on the shower and nothing comes out. >>More

Water Well Maintenance program

This service will keep the systems operating at peak performance, extend the life of the system equipment, inform the clients of potentially harmful bacteria in their well, identify many potential failures in advance, annual water level check. >>More

How to Chlorinate Your Well

1. Turn Off Power to submersible pump (located in fuse panel)
2. Bypass water softener
3. Remove bolts from well cap
4. Pour in 2 gallons of liquid bleach
5. Pour in 5 gallons of clean water
6. Re-install bolts on well cap make sure not to pinch wires
7. Turn on power to submersible pump

Iron bacteria are commonly cited as the culprit for any “slime” problems found in a well. Interestingly enough, though, only a very small percentage of the slime seen in wells and pipelines is actually iron bacteria (also referred to as iron oxidizing bacteria or by its proper name, Gallionella). Most of the slime formation found in wells is by naturally occurring soil bacteria, not iron bacteria. >>More
